BOX-CLOSURE Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed August 31, 1909. Serial No. 515,517.

To all whom it may concern:

Be it known that I. Anus I I. McALLisTisn, a citizen of the UnitedStates, residing at Millersville, in the county of Lancaster and Stateof lennsvlvania, have invented certain new and useful Improvements inBox- Closures, of which the following is a specification, referencebeing had therein to the accompairring drawing.

My invention relates to an apparatus for closing and pressing the topsupon boxes or cases, such as tobacco cases, which have been opened forthe purpose of sampling the contents and upon which, owing to theexpansion of the contents, the cover has to be forced thereon until itcan be retained by the proper nailing.

The objects of the invention are to produce a device of this class thatmay be easily and quickly applied to the case and is of such form thatby .a slight exertion of the operator great pressure on the cover may beobtained.

\Vith these and other objects in view my invention consists in certainconstruction and combination of parts as will hereinafter be fullydescribed and claimed and illustrated in the accompanying drawings,which form a part of this application; but it is fully understood thatwhile I have here described my invention as here illustrated, that I donot confine myself to the exact design as shown, as slight changes maybe made in the construction and arrangement of the several parts withoutdeparting from the spirit of the invention.

In the drawings :-The figure is a perspective view of the device asapplied, and the cover secured for nailing; while the dotted lines showthe position of the device before pressing.

Referring to the drawings, 1, indicates a pressing block, upon which,and parallel thereto, is journaled the rocker-shaft 2, in the bearings3; while upon the ends of said rocker-shaft 2, are rigidly secured theoccentric members 4, and which are also attached to the ends of theV-shaped handle 5; while the points of said eccentric members 4, areprovided with the pins or studs 6, which are formed with a head 11, andwhich project therefrom atright angles to the outerpart thereof the loop10, the sides of which are farther apart near the lower portion for thereception of the head 11, of the stud (3, allowing the head 11, to passtherethrough; while the sides of the loop farther up or toward the endof the arm are nearer togcther and will retain the loop from slippingoff of the stud 6; this arrangementbeing for the purpose of quicklydisconnecting the arms.

The operation of the device as a whole is as follows :The pressing blockhaving been placed upon the lid of the case and the gripping arms put inplace with their lower ends in engagement wi the bottom of the box andtheir upper .tecured upon the studs 6, with the hand; .a a verticalposition; the handle is then pulled down thus exerting an upward pullupon the gripping arms, and as the studs rise upward and pass over thecenter, the gripping arms will be held in their farthest upward positionwithoutfurther exertion on the part of the hand-lever until the box lidcan be permanently secured in place.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is In a box closure, in combination with apressing block having a rocker shaft mounted thereon, of a handlesecured to the ends of said shaft, rocker arms secured to the ends ofsaid handle adjacent to said shaft, studs formed upon the ends of saidarms and projecting atright angles therefrom, and a gripping armdetachably mounted upon said studs and adapted to engage the bottom ofthe. box.

In testimony whereof I atlix my signature in presence of two witnesses.
